  • Oil hydraulic system
    The motor control avoids the delayed transmission through hydraulic lines, allows the independent adjustment of several motorized outputs by central pressure means supply, returns the excessive energy to the input. .... In the comparison for pump control (primary control), shows the preferences following the motor control: good regulating…
  • Building technique for drinking water
    Computational operating point on the pump characteristic (PKL) or below, central throttling. .... In the central throttle, the excess between computational operating point and PKL is reduced. .... to reduce in a decentralized throttle results from the pressure loss for the hydraulically most unfavorable circulation…

  • CR4 - Thread: Gas Motor vs. Electric Motor - Equal HP?
    After that I hit some catalogs (McMaster, Grainger, Surplus Center , etc) and found that most manufacturers will sell units with either an electric motor or a gas engine of 3 times the hp of the electric motor. .... Some of the unit converted have included water pumps , winches, material handiling equipment, welders, conveyor belts, hydraulic drives, cement mixers and a golf/utility cart.
  • Oil hydraulic system
    promoted the excess current to the tank flows. .... The almost pressureless circulation of the pump conveying current submits to the middle position of (locking zero position) the directional valve as the connection with the tank Y of the pressure balance is connected. .... follows from it that a particularly large power saving follows against a conventional hydraulic system with locking…
